Detailed Description
As shown in fig. 1, the heat dissipation device capable of safely operating the cabinet-type electrical equipment disclosed in this embodiment mainly includes a closed housing 1, a heat dissipation water tank 2, a cold water tank 3, a water pump 4, and an exhaust fan 5.
As can be seen from fig. 1 and 2, the side surface of the closed casing 1 is provided with a movable door 11 which can be opened and closed, and the bottom surface is provided with two pairs of universal rollers 12, so that the pair of universal rollers can be self-locked for facilitating the movement and locking of the device.
The bottom of the inner cavity of the closed shell 1 is provided with a partition plate 13, the electrical equipment SB and the cold water tank 3 are arranged on the partition plate, and the heat radiation water tank 2 is arranged on the top surface of the electrical equipment. And normal-temperature water is respectively added into the cold water tank and the heat dissipation water tank, and the cold water tank is communicated with an external normal-temperature water source.
The water outlet pipe of the cold water tank 3 is connected with a regulating valve (not shown in the figure).
In order to facilitate the installation and maintenance of the water suction pump 4 and the regulating valve, the top surface of the closed shell 1 is provided with a step shape, the water suction pump 4 is arranged on the step surface, a water outlet pipe of the cold water tank 3 penetrates through the side wall of the closed shell 1 to be connected with an inlet of the water suction pump 4, and an outlet pipe of the water suction pump 4 penetrates through a top plate of the closed shell 1 to be connected to the heat radiation water tank 2.
A heat exchange tube bank is arranged in the heat dissipation water tank 2, the water inlet end of the heat exchange tube bank is communicated with the water outlet pipe of the water suction pump 4, and the water outlet end of the heat exchange tube bank is communicated with the cold water tank through a pipeline 6.
The exhaust fan 5 is located in the closed shell 1, and in order to facilitate installation and reduce the size of the closed shell, the exhaust fan adopts an axial flow fan, two ends of the axial flow fan are respectively connected with an air inlet pipe and an air outlet pipe, the air inlet pipe extends into an inner cavity of the electrical equipment SB, and the air outlet pipe extends out of the closed shell 1.
In order to facilitate circulation, an air inlet is formed in the side wall of the closed shell 1, and a filter screen is arranged at the air inlet so as to prevent impurities in the air from entering the closed shell. And the side wall of the shell of the electrical equipment is provided with a heat dissipation hole communicated with the inner cavity of the closed shell. In a similar way, the outer end of the air outlet pipe of the exhaust fan is also provided with a filter screen so as to prevent sundries in the air from entering the closed shell when the exhaust fan is not used.
An ice crystal pad 7 is arranged between the partition plate 13 and the bottom plate of the closed shell 1.
The heat dissipation of this device includes water-cooling heat dissipation and forced air cooling heat dissipation, specifically as follows:
when the temperature in the closed shell 1 is overhigh due to the heat generated in the working process of the electrical equipment SB, the device can radiate heat in an air cooling and water cooling mode, and can independently adopt the water cooling, air cooling or adopt the water cooling and air cooling mode simultaneously according to the season selection.
In the working process of the electrical equipment, the water temperature in the heat dissipation water tank 2 rises, when the water cooling mode is independently adopted for heat dissipation, the water suction pump 4 works to send water in the cold water tank 3 into a heat dissipation pipe row in the heat dissipation water tank 2 to exchange heat with high-temperature water in the heat dissipation water tank and then flow out, and the water returns to the cold water tank 3 through the pipeline 6 to circulate. During the cycle, the temperature of the water in the radiator tank 2 gradually decreases, and the temperature of the water in the cold tank 2 gradually increases. When the water circulated into the cold water tank 2 is insufficient to lower the temperature of the heat radiating water tank 3, the hot water in the cold water tank 3 is discharged to the hot water tank, and the cold water tank is replenished with normal temperature water and then circulated. The water in the hot water tank is cooled and then returns to a normal temperature water source.
When independently adopting the forced air cooling heat dissipation, air exhauster 5 takes out the hot-air in electrical equipment SB inner chamber toward outdoor, and outdoor low temperature air gets into the enclosure inner chamber from the air intake on enclosure 1 simultaneously, and the louvre through the electrical equipment lateral wall gets into in the inner chamber of electrical equipment simultaneously, reduces the temperature in the electrical equipment inner chamber.
The water cooling and air cooling modes are independently adopted, the solar heat collector can be used in spring and autumn with low air temperature, and whether heat dissipation is needed or not can be determined according to actual conditions in winter with low air temperature.
In summer with high temperature, the mode of simultaneously cooling by water and air can be adopted, and the specific principle is the same as the above. The heat can be dissipated by the mode of absorbing heat through the state conversion of the ice crystal pad.
According to the structure and the heat dissipation principle, the device can take away heat through water circulation, take away heat through circulating air current, and take away heat through the ice crystal pad to adjust the temperature in the closed shell, so that the electrical equipment in the closed shell can safely operate at a set temperature.
